JDK9s Modules offered preliminary isolation for packaged module structures, however at an application level module accesses should be rule defined. Spring Modulith with ArchUnit and jMolecules, established package relationship, restricted accesses and validates relationship during tests. By default, a module can access the content of any other module but cannot access subpackages of other modules. https://blog.frankel.ch/spring-modulith-modularity-maturity/ Benefits of using Spring 6 in terms of ORM, Text blocks to hold SQL in query annotation, Records to define DTO, UUID as basic type in JPA 3, JP

It used JDK 17 as a baseline, and Jakarta EE 9+ with specifications for Servlet 6.0 and JPA 3.1 facilitating access to Tomcat 10.1 and Hibernate ORM 6.1 respectively. Spring application contexts support AOT transformation processing as part of GraalVM Native image used in tandem with Spring Boot 3. Spring 6.0 enables the usage of Project Loom's Virtual threads feature and Project CRaC with checkpoint restoration for faster JVM startup and many other features. https://spring.io/blog/2022/11/16/spring-framework-6-0-goes-ga Establishing a good degree of isolation can vary regarding deployment (Microservices) or DDD-bounded context.

By extracting the exception handling block to a class, Lombok annotation SneakyThrow, Apache Commons Lang Failable stream API, and Varv functional library with Streams offers alternatives for handlezing the try/catch scenario embracing code pipe flow, thereby optimizing lambdas in the Streams. https://blog.frankel.ch/exceptions-lambdas/ When we package and ship our application to the clients, making it evident on the dependencies (both stated and transitive) used in the application aids clients in making informed decisions, adhering to any defined standards,

Prerequisites GraalVM JDK 11 distribution ( https://github.com/graalvm/graalvm-ce-builds/releases/tag/vm-22.3.0 ) - ensure you revise the JAVA_HOME and PATH appropriately Native Image executable (for windows, https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16 ) Maven build tool IntelliJ IDE MySQL Windows 10 OS We will commence by downloading a Spring template with Spring Boot >=2.7.5 version running on JDK 11 with the dependencies for Gr
